硬辊加工工艺改进

为延长轧辊使用周期，提高单槽轧制量，减少崩废槽现象，特优化硬辊加工工艺，提高硬辊加工质量及加工效率。

In order to prolong the service life of roll, increase single groove rolling capacity and reduce the occurrence of groove breaking and abandonment, the machining process of hard roll is especially optimized to improve the machining quality and efficiency of hard roll.
